NOAH a. WHITE, or nEn-Tn; cononnno LEVELING ATTACHMENT Fon HRAsH ING AND oTHER MACHINES Application filed December 11, 1925. Serial 1161225342,

This invention relatesto levelingdevices,

and has for one of its objects to provide a novel device of this character which shall be position so as topermit them to operate at their l'iighest efiiciency and so as to permit them to be operated with the least possible strain on their drive belts and on the tractors or other power plants. I

*The invention has for another ob ect to provide a device of the character stated Which shall be adapted to indicate any transverse or longitudinal deviation of the machine from the horizontal and which shall be adapted to be secured to a sill or other suit able part of a separator, whereby to permit the machineto be leveled with less labor and in shorter time than is now possible.

The invention has for a further object to provide ade vice of the character stated which shall'embody angularly related spirit levels and a bracket to which the levels are secured and which shall beadapted to be readily secured to the sill or other suitable part of the machine.

With the foregoing and other objects in view, the nature of which will appear asthe description proceeds, the invention consists in the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is a View partly in top plan and partly in horizontal section illustrating the application of the leveling device to a thrash- 'ing machine or other separator;

Figure 2 is a perspective View of the leveling device; t

Figure 3 is a sectional view taken on the verticalplan es indicated by the line 33 of Figure 1;

Figure 4 is a bottom plan View of the leveling device, and

Figure'o is a perspective view of the brack et or the leveling device.

' The leveling device comprises levels 1 and 50 2. The level 1 is longerthan the level 2. In

other respects, the levels 1 and 2 are similar,

and'a-s shown each comprises a stock 8 which maybe niadefrom wood or metal and is provided in thefrontsidethereof with an arcuate groove tor-the reception of a s milarly formed glass tube 1.. The tube a is filled with a suitable liquid in a manner to provide an air bubble The tube el is held in place by a plate 6 provided with end pieces or blocks 7 and secured in place by screws 8. The stock 3 is provided immediately above thespirit tube 1 with a downwardly and rearwardly inclined or b veled arcuate portion which bears a scale 9 marked with graduations calibrated ininches,thezero point 9a of the scale being located centrally between the ends thereof. i o

The levels 1 and 2 are arranged in right angular-relation. The stocks 3 have their adjacent ends beveled, as at 10, and aresecured together'by a plate 11 which is, re-' cessed'in the upper sides of the ends of the steaks and is secured in place by screws 12.

The levels 1' and 2 are carried by a bracket 13 havlngrlght angularly related long and short arms l land 15, respectively, and a, web

arrangedbetween the frontedges ot' the arms and having an arc-uate edge 17 and an opening 18. the long arm 14 and the level 2 on the short arm 15 of the stock 3 with their outer sides of the same vertical plane with the rear edges of the arms and with the web 16 extending forwardly beyond their front sides The levels 1 and2 are secured to the bracket 13 by screws 19, t

In practice, the leveling device is secured to the sill 20 of a thrashing machine or other separator 21 with the bracket 13 resting upon the sill in a manner to arrange the level 1 The level 1 is arranged on.

longitudinally and the level 2 transversely of the machine, as clearly shown inv Figures 1 andB. The level 1 and the rear edge of the bracket arm-14c are preferably arranged in contact with the adjacent side 22 of the machine. A bolt 23 passing through the opening 18 of the bracket 13 and through the sill 20, secures the leveling device firmly in place. As the leveling devices 1 and 2 extend respectively longitudinally and trans v .c 1 f r 1,?87,807

versely'of the machine, and as thescales 9 are calibrated in inches, the extent that the machine should be raised or lowered at one or'morecorners thereof, in order to efl'ect wthe levelingof the machine, mayibe readily f ascertained. The machine may be leveled by meansof blocks or by digging one or more holes in the ground for'the reception of one or more Wheels of'the machine.

10 From; the toregoing description, taken in connection with the accompany ngdravvmg, I it will be understoodthat the leveling device 7 is simple, durable and highly etficient,'jthat' it may be manufactured. and sold at low I 5 cost, that its spirit tubes are amply protected from injury, and that it may be easily and quickly Secured to the machine. 1

lVhile I, have described the principleof the invention, together with the device which I now consider to be'th'e best embodiment thereof, 1 WlSll it understood that the struc- V lure shown is merely illustrative and that such changes may be made therein as fall Within the scope of the invention andclaim.

25 \Vhat I claim is: V i p I v A leveling attachment for a machine comprising a horizontallydisposed bracket hav- 'ing angularly related arms provided with plain fiat upper faces and a connecting web 30 arranged in and between the frontedges of the arms and having an attaching bolt receiving opening therein, a vertically disposed level stock arranged upon the upper face of each arm With its rear face in the same vertical plane Withthe rear edge of its respective bracket, and said, level stocks having their adjacent ends beveled and arranged in abutting relation, and means securing the levelstocks to the bracket rearwardly of the I 49 Web. y

In testimony whereof I afiix my signature.
